Power Mirror Switch Inoperative

Remove power mirror switch. See POWER MIRROR SWITCH under REMOVAL & INSTALLATION. Using an ohmmeter, check resistance and continuity between appropriate power mirror switch terminals. See Fig 1 . See POWER MIRROR SWITCH RESISTANCE and POWER MIRROR SWITCH CONTINUITY tables. If resistance and continuity are not as specified, replace power mirror switch.
